Triple threats

Jean Segura and Michael Bourn, filling the top 2 spots in Chip Hale's batting lineup, combined for 6 hits, 4 runs and had 2 of the D-backs' 3 triples in Tuesday's 7-5 win -- pushing the team total to a major-league leading 33 three-baggers. (The Giants are next with 27.) Segura has a 9-game hitting streak (16 for 39, .410) to push his average to .318. Bourn, playing every day in center field due to injuries to Chris Owings, Socrates Brito and David Peralta, is 19 for 53 (.358) over his past 13 games, raising his average from .235 to .280.

#VoteLamb campaign cranks back up

Jake Lamb -- 1 of 5 players in the Final Vote for the NL All-Star roster -- will be back in the lineup tonight after a respite on Tuesday against Padres' lefty Christian Friedrich. Even that didn't slow his attention-raising onslaught, as he came off the bench as a pinch-hitter and delivered his National League-leading 7th triple. It was his 45th extra-base hit (one behind league-leader Nolan Arenado) and lifted his slugging percentage to .617. In 18 games since June 17, he's hitting .391 (25 for 64) with 5 triples, 7 home runs and 19 RBI.
